Patent Court Decision, 2019Heo7825, decided April 16, 2020 (‘ ’ Case)

Although the claimed trademark  may deemed to have a slightly designed
letter “P”, the degree thereof is limited to having the shape of a rounded
rectangle instead of the semicircle, still falling short of being perceived by
ordinary consumers or traders as something more than a simple and common
alphabet letter “P” or a newly created figure that would generate special
attention such as a “tennis rocket”, “household broom”, or “Chinese kitchen
knife” as the plaintiff argues. Furthermore, as long as the claimed trademark
is nothing more than a slightly stylized version of alphabet letter “P”, it
would not be appropriate that the plaintiff has the sole right to use the mark
stylizing alphabet letter “P” in a simple and easy manner.
The claimed trademark is a “trademark that consists solely of a simple and
common mark” under Article 33(1)(vi) of the Trademark Act.
